Hi team, I am using Orin NX 16GB with a custom carrier board, R35.3.1, I modify the dts to config the usb otg port as a host. like this ```auto xusb_padctl: xusb_padctl@3520000 { status = "okay"; pads { usb2 { lanes { usb2-0 { nvidia,function = "xusb"; status = "okay"; }; usb2-1 { nvidia,function = "xusb"; status = "okay"; }; usb2-2 { nvidia,function = "xusb"; status = "okay"; }; }; }; usb3 { lanes { usb3-0 { nvidia,function = "xusb"; status = "okay"; }; }; }; }; ports { usb2-0 { - mode = "otg"; + mode = "host"; status = "okay"; vbus-supply = <&p3509_vdd_5v_sys>; #if TEGRA_XUSB_DT_VERSION >= DT_VERSION_3 usb-role-switch; connector { compatible = "usb-b-connector", "gpio-usb-b-connector"; label = "micro-USB"; type = "micro"; vbus-gpio = <&tegra_main_gpio TEGRA234_MAIN_GPIO(Z, 1) GPIO_ACTIVE_LOW>; }; #endif }; usb2-1 { mode = "host"; vbus-supply = <&p3509_vdd_av10_hub>; status = "okay"; }; usb2-2 {/* Goes to M2.E */ mode = "host"; vbus-supply = <&p3509_vdd_5v_sys>; status = "okay"; }; usb3-0 { nvidia,usb2-companion = <1>; status = "okay"; }; }; }; ``` and I plug a usb device to the port, and reboot the system, and it works well ```auto root@w:~# lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 002: ID 046d:c534 Logitech, Inc.

Hi, Is it a micro-B port on the carrier board? Please make sue the port is designed properly. The Xaiver NX and Jetson Nano carrier boards have micro-B port and it is designed to work in host mode only. For OTG port, you would need to have proper design for VBUS\_DETECT and ID pins. ---

It is not a micro-B port, the usb port of carrier board works well on Xavier NX, but failed on Orin Nx, so we should have the proper design. ---

Hi, This setting is for OTG port and not required for host-only port: ```auto usb-role-switch; connector { compatible = "usb-b-connector", "gpio-usb-b-connector"; label = "micro-USB"; type = "micro"; vbus-gpio = <&tegra_main_gpio TEGRA234_MAIN_GPIO(Z, 1) GPIO_ACTIVE_LOW>; }; ``` Please remove it and try again. If the issue still persists, please do compliance test to ensure D+/D- signals are good: [https://developer.nvidia.com/downloads/jetson-orin-nx-series-orin-nano-series-tuning-complinace-guide](https://developer.nvidia.com/downloads/jetson-orin-nx-series-orin-nano-series-tuning-complinace-guide) ---

Hi @DaneLL , the issue seems be related to “auto suspend” function of usb. when I disable the function, it works well. ```auto root@w:~# cat /sys/bus/usb/devices/usb1/power/control auto root@w:~# root@w:~# lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub root@w:~# root@w:~# root@w:~# echo on > /sys/bus/usb/devices/usb1/power/control [2113.268609] tegra-xusb 3610000.xhci: Firmware timestamp: 2021-12-01 05:27:10 UTC, Version: 80.03 release root@w:~# [2113.632018] usb 1-1: new full-speed USB device number 4 using tegra-xusb [2113.789991] usb 1-1: New USB device found, idVendor=046d, idProduct=c534, bcdDevice=29.01 [2113.790254] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [2113.790468] usb 1-1: Product: USB Receiver [2113.790587] usb 1-1: Manufacturer: Logitech [2113.796679] logitech-djreceiver 0003:046D:C534.0009: hidraw0: USB HID v1.11 Keyboard [Logitech USB Receiver] on usb-3610000.xhci-1/input0 [2113.860161] logitech-djreceiver 0003:046D:C534.000A: hiddev96,hidraw1: USB HID v1.11 Mouse [Logitech USB Receiver] on usb-3610000.xhci-1/input1 [2113.922525] logitech-djreceiver 0003:046D:C534.000A: device of type eQUAD nano Lite (0x0a) connected on slot 1 [2113.924550] logitech-djreceiver 0003:046D:C534.000A: device of type eQUAD nano Lite (0x0a) connected on slot 2 [2113.933022] input: Logitech Wireless Keyboard PID:4023 as /devices/platform/3610000.xhci/usb1/1-1/1-1:1.1/0003:046D:C534.000A/0003:046D:4023.000B/input/input26 [2113.933854] logitech-hidpp-device 0003:046D:4023.000B: input,hidraw2: USB HID v1.11 Keyboard [Logitech Wireless Keyboard PID:4023] on usb-3610000.xhci-1/input1:1 [2113.940495] input: Logitech Wireless Mouse as /devices/platform/3610000.xhci/usb1/1-1/1-1:1.1/0003:046D:C534.000A/0003:046D:4058.000C/input/input27 [2113.941054] logitech-hidpp-device 0003:046D:4058.000C: input,hidraw3: USB HID v1.11 Mouse [Logitech Wireless Mouse] on usb-3610000.xhci-1/input1:2 root@w:~# root@w:~# root@w:~# root@w:~# lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 046d:c534 Logitech, Inc.

Sorry for the late response, is this still an issue to support? Thanks If it works by disabling auto suspend, it looks to be a fine solution. ---
